The effect of quarry waste dust and reclaimed asphalt filler in hydraulically bound mixtures containing plasterboard gypsum and GGBS

In this research, a novel Hydraulically Bound Mixture (HBM) is successfully developed using waste minerals and industrial by-products to fully replace cement in road (base) foundation materials. HBM mixture that sets hardens by hydraulic reaction usually has compaction rolling. The materials used were reclaimed asphalt filler (RAF), quarry dust (QWD), plasterboard gypsum (PG) ground granulated blast furnace slag (GGBS). A statistical design programme – Minitab 18, was for the of experiment. Compressive strength, high pressure flow tests freeze/thaw carried out determine mechanical stability by-product binders performance determined strength development time. It concluded can be 100% replaced with named by-products. Test results revealed presence GGBS highly beneficial between 40 60% replacement weight. Strength on paste comprising reduced during first 28 days. After days up 90 when maximum gained, increases 60%. showed top four mixes two groups discussed research meet standard requirements
